    The AWS Athena Workgroup is unencrypted. Encryption protects query results in your workgroup.
    To enable, add: `encryption_configuration { encryption_option = "SSE_KMS" kms_key_arn = 
    aws_kms_key.example.arn }` within `result_configuration { }` in your resource block, 
    where `encryption_option` is your chosen encryption method and `kms_key_arn` 
    is your KMS key ARN.
